A kolacky is a small dinner roll-like pastry which is folded, enclosing filling in the center.
The most common fillings include Cottage Cheese, prune, poppyseed, apricot, apple, blueberry and raspberry.
both open-faced and closed-face kolackys were made in Czechoslovakia.
the closed kolacky came into being because the fruit in the open-faced buns would get all over the working man's lunch bucket. The men had their wives fold over the pastry so it wouldn't mess up the other things in the lunch bucket.
This is a old recipe from my grandmother who came from Prague Czechoslovakian at the turn of the 20th century.
